The Most Divisive?

Here's a top 11 in order of divergence of opinion
(It's actually based on standard deviation of score which is probably a good enough proxy)

The Alchemist
Atonement
The Leopard
The Child That Books Built
The Bridegroom
Noughts & Crosses
London Fields
Moby-Dick
The Origin Of Species
Beloved
Layer Cake

All but two of the above are choices from over 4 years ago. This could suggest we're better able to judge a books reception. Alternatively we could all be playing safe. (Then again it could be neither. Thats Stats for you! )

My recollection is that the only books that provoked much argument / discussion were The Alchemist & Moby Dick (I think I conceded that "The Origin Of Species" was a selfish choice. I also put myself at a disadvantage defending "London Fields" since I hadn't finished re-reading it!)
